Lean canvas by Ash Maurya ready to use in Obsidian.
You'll need the Obsidian app installed.
After downloading the lean canvas folder from GitHub, pick the "open folder as vault" option in Obsidian.
You can then start filling your business model canvas. The template has a bunch of Markdown files, one for each box or building block. The .canvas file gathers all these text files together. You can input text on each .md file separately or type everything in the single .canvas document.
If you find this template useful and would like to support its development, you can sponsor me on Github, or buy me a coffee.
